My basketball coach at Princeton used to say, "On the court, you can tell who is selfish(自私的)."

   When my sister Michelle brought Barack Obama home to meet the family, she said to me, "I want you to take him out to play, to see what type of man he is when he’s not around me." So I invited Barack to play basketball with a few friends of mine.

   I was very nervous although I had already met Barack a few times. I was thinking this guy seemed like a good guy. We played a hard five-on-five. He was thin but not weak. He played extremely left-handed. He dealt with everything perfectly. He wasn’t the best guy out there or the worst guy. I liked the fact that he was confident but wasn’t proud. Barack was very team-oriented (有团队精神的), very unselfish. He played as if he was one of us —he wasn’t trying to be president of Harvard Law Review. But the best part about it was that when we were on the same team, he did not pass me the ball each time. He wasn’t trying to suck up to my sister through me. I was glad to give my sister the good news, "Your boy is straight."

   He isn’t selfish, which is the greatest praise you can give both a player and a leader. America has got a guy who is running a government in an efficient (有效率的) manner. That’s the same guy I got to know playing basketball when he was visiting my family.
